. i Specification of Letters Patent. Patgnted NOV. 16 1920 Application filed September, 1919. Serial No. 321,303.

To all whom it may concern.' Y

Be it lrnown thatA I, JACOB KAUFMANN, a citizen of the United States, residing at Philadelphia, and State of Pennsylvania, have invented certain new and usefulv Improvements in Heddle-lilrames, of which the following is a' bars Yintermediate their ends which will securely support said bars against undesir-l able motion, but which will, however, permit the same to bereadily mounted in and A further object of my invention is' to pro-` vide a device for supporting the heddle bars intermediate their ends which may be.

readily adjusted to 'properly position the supporting surfaces with respect to the heddle bars, which will afford a maximum of support for said bars, and which is so constructed and arranged as to provide a maximum of reserve metal adjacent the bearing' surfaces to thereby increase lthe life of the supporting device.V

My present invention contemplates an iinproved form of device which is simple, durable and efficient for its intended purpose, and which is particularly adaptable for that type of heddle frames in which there are provided pairs of heddle bars at the top and bottom as is often done when warp ends controlled by the frame are closely arranged. Y The nature and characteristic features of my invention will be more readily understood from the following description taken in connection with the accompanying drawings forming' part hereof, in which;

Figure 1 is a front elevation of a heddle frame, with supporting devices embodying the main features of my present invention shown mounted therein;

Fig. 2 is an enlarged detail view showing one of the supporting devices of my present invention and portions of the heddle frame and bars; and

Fig. 3 is a transverse sectional detail view,

in the county of PhiladelphiaV novell portion of my dismounte'dl from 'the frame when desired.l

` the section being taken approximately on the line 3- 3 of Fig. 2.

Referringr to the drawings, the heddlel frame there shown comprises the top and bottom rails '5, usually made of wood, and connected at their respective ends by means of the end straps 6, extendingfrom end to end of the heddle frame, and arranged near 'the top and bottom rails in the usualmannerarejthe heddle bars 7, upon which the heddles 8 are mounted and supported. The heddle bars 7 may be arranged vin pairs as shown, this arrangement being provided for Yclose installations of the wrap ends` to prevent crowding of theheddles on their supporting bars. i

VThe device for supporting the heddle bars intermediate their ends whichf'comprises lthe presentv invention'includes a bolt 1Q' which is threadedfthroughout the'greater portion of itsclength and through an aperture llfwhi'ch eX-Y tends vertically through the rail 5. The

bolt 10 is not in threaded engagement with the rail 5 but is capable of being vertically adjusted therein. A nut 12 is threaded on the bolt 10 in a position to the inside of the inner edge of the vrail 5, and a washer 13 is interposed between said nut 12 and said inner edge of the rail 5. A'nut 14 is also mounted on the bolt 10 in a position to the 'outside of the outer edge of the rail 5. The

nut 14 is preferably of the wing type, to facilitate the manipulation thereof. A washer 15 is also arranged on the bolt V14 adjacent the outer edge of the rail 5, and a split lock washer 16 is interposed between the washer 15 and the wing nut 14.

The inner end of the bolt 10 is flattened at 20 to providey a relatively wide portion on each face of which a plate 21 is secured, preferably by means of rivets 22 which pass through said plates and flattened end of the bolt 10. Each plate 21 is provided with slots 23 arranged on the sides of the iattened end 2O of the bolt 10, and these slots are open toward the rail 5 in which the supporting device is mounted. One of said slots 23 is provided for each heddle shifting stresses and separated, giving the eli'ect of a Wide bearing and thus` minimizing Wear at the points of Contact. ,Y v

In the operation ofthe loom all parts of theY harness are subjected to continually knocks which results in rapid` Wear at certain parts, tending to clestrtution and d isarrangement.l Hereto- Y fore,l considerable dlihculty has occurred on nso account of4 the various types of supporting hoo is .employed and permitting theheddle bars to ioul on adjacent frames. In the present construction,T this diiicultyis largely overcome by the prio, ,vi s,i`o,nV ofthefmetal'ofa considerable a extent beyond," the slotsin.Whichr the heddle bars are.Supported'.,V

Furthermore, the supporting'l device is so Y arranged that thel `sameY may be adjusted, both initially and from time totime to compensate for'weanso that. the.V heddle bars Willlbe, firmly, held, and Wear 'and'` danger, of dsarrangement is .in this manner minimized. TheY operation of effecting.r theA adjustment being only necessary to vIY claim as new and yends comprising a bolt quickly Wearing through .ends` comprisingr a bolt nut, 14 after Which the j nut 1.2, Whichis adjacent theinner edge of Y the rail 5, is brought to the proper location on the bolt l0, and, after the Wing nut 14 is then tightened, the adjustment of the kdevice Will remain secure.

aving' thus described the nature and characteristicfeatures of'my invention, What desire to secure by Letters atent is:

1. In a heddle frame,

Y the means for supporting the heddle bars intermediate their passing through a portion of the frame, means for securing said bolt in adjusted positions insaid frame, one end ofsa'id bolt being flattened, a plate secured on each side osaid iattened portion of saidbolt, said platesv provided With slots yin Whichthe andsaidslots,being open atone end. y

v2., In aheddle frame, the means for supporting the heddle bars intermediate their passing,` through a ,portionvof the, frame,1 said bolt in adjusted positions: in said frame,

one end of said bolt being flattened, a plate securedon eachI side-of said flattened portion of'said bolt, saidlplatesrprovided with slots in Whichthe-heddle slotsbeingfopen at their ends toward the portionl of; the framein; Which the' device is mounte d and said plates having a considerable extentof` metal'I beyond said slots;
